<h3><font color=#0000e0><strong>History and Status:</strong></font></h3> |
| |
|
| <p> |
<p> |
| |
The Sun3 port of OpenBSD was derived from the NetBSD/sun3 port, when the sun3 and sun3x |
| |
ports were still different entities. The tiny bits of OpenBSD that are |
| |
completely specific to the Sun3 port are basically the same as their NetBSD |
| |
counterparts. |
| |
</p> |
| |
|
| |
<p> |
| |
<h3><font color=#0000e0>Supported Hardware:</font></h3> |
| |
OpenBSD/sun3 runs on the following Sun-3 models: |
| <ul> |
<ul> |
| <li>default data resource limit raised to 16384 Kbytes so that "make build" |
<li> Sun-3/50 |
| does not crash in libc. |
<li> Sun-3/60, 3/60LE |
| <li>/dev/leds derived from |
<li> Sun-3/75, 3/140, 3/150, 3/160 and 3/180 |
| <a href="http://www.NetBSD.org/cgi-bin/query-full-pr?2172">NetBSD pr#2172</a> |
<li> Sun-3/110 |

<li> Sun-3/260 and 3/280 |
| </ul> |
</ul> |
| |
Other Sun-3 models are NOT supported, especially 68030-based ones (<a href="sun3x.html">sun3x</a>). |
| |
</p> |
| |
|
| <hr><p> |
<p>Supported devices: |
| |
<ul> |
| |
<li> On-board serial ports |
| |
<li> Sun type 3 keyboard and mouse |
| |
<li> On-board or VME video (bwtwo, cgtwo, cgfour) |
| |
<li> On-board or VME ethernet (intel, lance) |
| |
<li> On-board or VME sun-3 scsi controller, currently with some limitations |
| |
<li> VME xylogics cards are recognized but currently not working |
| |
</ul> |
| |
The sun-2 scsi controller is not supported yet. |
